AWhat changed
Demonstrated strontium atoms trapped near a magic wavelength with narrow clock spectroscopy.
Scientific scope
The record is the exact four-author 2005 Nature paper and its reported strontium apparatus and measurements. It does not absorb later optical-clock accuracy records, other atomic species or all lattice-clock engineering.
